<p>The silk screen decorating machine comprises: a belt-shaped flexible silk screen (1) ring-wound and stretched between two parallel-axis rotors (2, 3) by at least one of which the screen (1) is drawn; means for spreading a decorating fluid and causing the fluid to pass through the screen (1). The parallel-axis rotors (2, 3) are arranged projectingly above a mobile plane (21) for conveying tiles (22) and are constituted by pairs of wheels (4, 5), on which the screen (1) partially windingly couples. The wheels (4, 5) are mounted on respective shafts (6, 7), which shafts (6, 7) are each constituted by a first segment (8) and a second segment (9) which are coaxial, solid in rotation and axially displaceable one with respect to another. The wheels of each pair of wheels are mounted solidly, one of each pair on a first segment (8) and one of each pair on a second segment (9). Also provided are means for interacting on command with free ends of the shafts (6 and 7) so as to position the shafts (6 and 7) at a predetermined reciprocal distance. <IMAGE></p> |
